摘　　要：为使变电站达到可靠性、功能性和经济性要求,人们常采用内桥接线作为电网终端变电站项目的电气主接线。对此,要求技术人员在变电站的设计过程中,充分考虑终端变电站的特点,认真分析电气二次电流回路、电压回路和备自投逻辑回路的特点,使其满足变电站的运行维护及扩建要求。Inner bridge connection is used as the main wire in terminal electrified wire netting of the substation to make itreliable, functional and economical. Technicians therefore are required in their design to take full consideration of the features of the terminal substation, analyze carefully the characteristics of the electric secondary circuits, voltage circuits and the emergency power supply autorestart circuit to meet the demands of the substation maintenance and expansion.
